About TMC

In 2000, Robert Van Hook and Jackie Eder-Van Hook traveling on a year-long sabbatical conceived of Transition Management Consulting, Inc. (TMC) as a consulting firm dedicated to supporting associations and nonprofits during leadership transitions.  They wanted to merge association management operations skills with a deep understanding of human and organizational dynamics. TMC Vision and Mission.JPG

TMC provides just in time, customized executive services to meet imminent or urgent needs for executive-level management for associations and nonprofits in transition through interim executive leadership, executive search, and succession and transition planning.

TMC’s interim executive management engagements are triggered by the departure of an executive, a challenging transition period and opportunity for organizational change. By utilizing interim leadership, the organization has time to assess the organization – time to consider what is working well, what is not working well, and what can be improved or changed. TMC’s professional interims provide a set of fresh eyes and independent perspective that only an outsider can provide.

Executive transitions are an opportunity for organizational assessment and renewal, not simply as a crisis requiring an immediate solution or search. The hallmark of our executive transition services is our ability to integrate effective high level association management skills with change management. The breadth of transition and leadership succession experience of our founders and consultants is unparalleled in the association and nonprofit sector.

TMC supports all levels of change needed, including start-ups, incremental changes, stabilization, and turnarounds.

Our work as professional interim executives is to prepare the organization for its next staff leader, so the executive can hit the ground running. Let us help you achieve your organization's mission.
